This offence criminalises the act of “foreign interference”. To commit the offence, a person must be doing an activity for a foreign state, and the person’s actions must include all three of the following key elements – they:

know, or ought to know, they are acting for a foreign state, and
act in a covert, deceptive, coercive, or corruptive manner, and
intend to, or be aware that they are likely to, harm New Zealand interests specified in the offence through their actions.

This doesn’t really back up the claims you make in the body text, and this is the source you’ve provided to back yourself up.

First, factual reporting isn’t acting for a foreign state, unless they’re paying you a salary.

Second, there isn’t anything deceptive about reading, writing or sharing news articles.

Third, I struggle to see how this would harm NZ interests.

This is all very tinfoil hat, in my view.
